Another code - unable to proceed

Hi,I'm stuck at the start of Chapter 5. I'm in Lawrence's room and clicked on the painting at the end of the bed to trace the path of the bird except it won't let me do anything on the painting to trace the path. Have checked on a walk through and I haven't missed anything, so I have no idea why its not working. The erase button while on the picture isn't working either so I guess something is corrupt.Any ideas?Otherwise, anyone have a .sav file just the other side of the door?!Thanks ???

erm.... is there something in that walk through to help? Or did you possibly misread the question...?
